Add HistoryDatabase schema version 3 and customize section padding in ActivitiesScreen

- Add `HistoryDatabase` version 3 schema definition including the `history` table and its associated indices.
- Update `EventSection` and `TagsSection` components to accept custom padding parameters, defaulting to previous values for backward compatibility.
- Adjust `ActivitiesScreen` to use zero-padding and spacers for content and tags sections, improving the layout density of activity items.
